Hi Lou,
Thanks for the info! I am weighing up between a Saito FG84 radial or the DLA 4 cylinder. The saito sounds great but I am worried about power and reliability with it. The DLA seems a much simpler solution with buckets of power and the ability to swing a nice big prop.
I have flown a friend's Z Corsair about 18 years ago and it was a fun machine, especially as it only weighed 25lb. My thoughts on the tail wiggle is that the vertical fin is too small.
Good luck with your Corsair at Top Gun, that event is something I would love to do but it's a massive effort from Australia!
Cheers
Mick
